"The Register takes a look at spam touting everything from Viagra to phishing
sites being sent from Fortune 1000 networks. Oracle was found to have a
machine pushing out a PayPal phishing scam, and BestBuy had a system sending
thousands of spams a month. The Washington Post's Security Fix blog also is
tracking this story, finding stock spam being pumped from ExxonMobile and from
American Electric Power, among others. Another machine at IndyMac Bank was the
source of spam touting generic prescription drugs. From the story: '...an IT
engineer with American Electric Power, said the stock spam came from a
bot-infected computer belonging to a contractor at one of its power generator
plants.'"
